Question

How much heat energy is required to convert 99.2 g of solid iron at 25 °C to liquid iron at 1538 °C? The molar heat of fusion of iron is 13.8 kJ/mol. Iron has a normal melting point of 1538 °C. The specific heat capacity of solid iron is 0.449 J/g·°C.

Answer 1

\(q=m*C*\Delta T+\Delta H^o_{fusion}*n\)
